For example, if the colors of the image are red, blue, and green, the colors are emitted sequentially at a rate three times the desired frame rate of the display. The colors are emitted from a backlight unit (BLU) that produces pulses of colored light successively. By emitting colors sequentially, the number of subpixels in a pixel can be decreased or eliminated. Thus, among other advantages, the size of each pixel can decrease and the spatial resolution of the display device (e.g., pixels per inch) can increase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pulsed backlight unit in liquid crystal display device","description":"To increase the spatial resolution of a liquid crystal display (LCD) device, instead of emitting colors of an image (e.g., the three primary colors) in a single frame, the colors of an image are emitt","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11488551","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
